INTRODUCING THE EMISSION PROCESS OF HYDROGEN SULFIDE TO A SEWER PROCESS MODEL (WATS)

Emission of hydrogen sulphide in sewer network results in odour, health and corrosion problems. These problems generally occur when wastewater is transported under anaerobic and turbulent conditions; Studies on integrated aerobic/anaerobic processes in sewers have led to a conceptual sewer process model, WATS(Wastewater Aerobic/anaerobic Transformations in Sewers). Emphasis in this study is on an extension of the WATS model in terms of hydrogen sulphide emission. By applying the extended WATS model, users can more realistically cope with the fate of hydrogen sulphide.
